What's Difference Between Inch-Pound Torque and Feet-Pound Torque?
I have a torque wrench and want to use it to torque the spark plug
properly. The instruction calls for torquing it to 20-feet-pound. When I read the torque rating of other fittings, I came across some rating as 60-inch-pound. What's difference between the "feet pound" rating and "inch pound" torque rating? Which rating the torque wrench is supposed to use? The instruction manual of the torque wrench doesn't say anything about this, and the rating imprinted on the wrench simply says "Pounds". Is 60-inch-pound the same as 5-feet-pound (60/12=5)? Thanks in advance for any info. Yes, I know that the torque rating is for dry thread, not for thread that has been coated with anti-sieze compound. I have already read the past posts about this. Thanks anyway. Jay Chan |

One foot pound = 12 inch pounds. 60 inch pounds is 5 foot pounds.... and you will probably need a 1/4" drive torque wrench to do that.... -- Grady-White Gulfstream, out of Southport, NC. http://myworkshop.idleplay.net/ ----------------- www.Newsgroup-Binaries.com - *Completion*Retention*Speed* Access your favorite newsgroups from home or on the road ----------------- Thanks for pointing out that 60-inch-pounds is the same as 5-feet-pounds. Now, I am wondering if the pounds-rating of my torque wrench is in term of inch-pounds or feet-pounds. It doesn't say. Is this something supposed to be "understood" like "if it doesn't say, it must be feet-pounds"? Mine is a 3/8" torque wrench. I guess I will not be able to use it to torque to such a low torque rating. I guess I am better off using the trick of "turn 1/4 turn more after it has already been tight" instead of buying another torque wrench. Jay Chan |

Jay Chan This should help: http://www.srtorque.com/torqcon/tcip.html Thanks for the conversion table. This means 60-inch-pounds is the same as 5-feet-pounds. Sounds like this torque rating is quite commonly used. Jay Chan |

In dentistry, we tighten implant abutments to 35 N-cm. 1 lb-ft equals 135.5818 N-cm. If I assumed lb-ft when the manufacturer said "tighten to 35", I'd wrench the patient's head off. |
